C# 上载文件时显示模式

我正在构建一个c MVC应用程序，我想知道在上传文件时如何显示一个包含请等待消息的模式

我已经搜索了很多Goggle和这个网站，但我可以使用一些更直接的反馈

我已经在index.cshtml中创建了模式，但不确定在上传过程中如何显示它。我试着在我的提交按钮中使用类似的东西，但它没有发布表单

 data-toggle="modal" data-target="#myModal"

这是我的密码

Index.cshtml

<h4>Please fill out the form below and select at least one file to upload.</h4>

@using (Html.BeginForm("Index", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    <div class="row">
        <div class="col-md-2">
            <h5>Your Name:</h5>
        </div>
        <div class="col-md-4">
            <input type="text" name="uname" class="form-control" required placeholder="John Smith">
        </div>
    </div>
    <div class="row">
        <div class="col-md-2">
            <h5>Your Email:</h5>
        </div>
        <div class="col-md-4">
            <input type="email" name="email" class="form-control" required placeholder="test@test.com">
        </div>
    </div>
    <div class="row">
        <div class="col-md-2">
            <h5>Your Company:</h5>
        </div>
        <div class="col-md-4">
            <input type="text" name="company" class="form-control" required placeholder="Test Company, Inc">
        </div>
    </div>
    <div class="row">
        <div class="col-md-2">
            <h5>Choose file(s) to upload (Max 500MB):</h5>
        </div>
        <div class="col-md-4">
            <input name="files" type="file" id="files" multiple="multiple" class="form-control" required />
        </div>
    </div>
    <div class="row">
        <div class="col-md-2">
            <h5></h5>
        </div>
        <div class="col-md-4">
            <input type="submit" name="submit" value="Upload" class="btn btn-primary" />
        </div>
    </div>
}

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-body">
                Please wait while we are uploading your files
                <div class="progress">
                    <div class="progress-bar progress-bar-striped active" role="progressbar" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100" style="width: 100%">
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

这是我的控制器

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Net.Mail;

namespace vidup.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {

            return View();
        }

        [HttpPost]
        public ActionResult Index(List<HttpPostedFileBase> files)
        {
            var userName = Request["uname"].ToString();
            var userEmail = Request["email"].ToString();
            var userCompany = Request["company"].ToString();
            ViewBag.Username = userName;
            ViewBag.UserCompany = userCompany;
            ViewBag.UserEmail = userEmail;
            int i = 0;

            var path = Path.Combine(Server.MapPath("~/Uploads"), userCompany, userName, DateTime.Now.ToString("MM-dd-yyyy h-mm-tt"));
            if (!Directory.Exists(path))
            {
                DirectoryInfo di = Directory.CreateDirectory(path);
            }

            foreach (HttpPostedFileBase item in files)
            {
                i++;
                if (item != null && item.ContentLength > 0)
                {
                    var fileName = Path.GetFileName(item.FileName);
                    var fullPath = Path.Combine(path, fileName);
                    ViewBag.Message3 = fileName;
                    ViewBag.Message4 = fullPath;
                    try
                    {
                        item.SaveAs(fullPath);
                        var fileCount = i + " File(s) uploaded successfully";
                        ViewBag.Message = fileCount;
                    }
                    catch (Exception e)
                    {
                        ViewBag.Message = e;
                    }
                }
                else
                {
                    ViewBag.Message = "No File selected";
                }
            }




            return View("Status");
        }
    }
}

最后是status.cshtml

<h2>Upload Status</h2>

<h4>Thank you, @ViewBag.UserName from @ViewBag.UserCompany</h4>
<P>Your file upload returned a status of: @ViewBag.Message</P>
<p>An Email has been sent to @ViewBag.UserEmail with the status of this upload.</p>
<br/>
<a href="@Url.Action("Index")" class="btn btn-primary">Click here to upload again</a>

submit按钮不再发布表单的原因是，您在表单中添加的属性将覆盖其默认行为-除了模式显示之外，您还需要向其添加onclick处理程序以启动表单提交。给提交按钮一个ID，给表单一个ID。。之后，这是一个简单的onclick方法

$('buttonid').on('click', function()
{
  $('#formid').submit();
});

这会告诉您的按钮在每次单击时提交表单

这是我得到的，但它不起作用。getElementById'sbmtBtn'。单击，函数{$'upldFrm.submit；}；好吧，一定是缓存问题导致它现在在一个不知名的chrome窗口上工作。很高兴能提供帮助：同样，有没有一种方法可以轻松地将chrome在右下角显示的百分比显示为其上传进度条的百分比？查看此图像以供参考并非默认情况下，您可以轻松创建自己的进度条，但我认为您永远无法知道上载文件所需的确切时间，因此我认为有时页面在到达100%之前导航时，您会得到
